As show in the photo if you use this stainless ball valve in conjunction with the PCO 1881 Tee Piece and the Carbonation Cap, you will have the added advantage that you will be able to use CO2 gas to purge out oxygen from the hops before you dry hop.
Note - Dry hop pellets will require a bit of a shake to get them to fall through the 20mm
bore. If you tap the PET Coke bottle this should be enough to make the hops fall down into
the fermenter through the ball valve.
